"How to Clean Optics on $500 Or Less"

Found this lens cleaning primer on the “Company Seven” web site. What do you think about this way of cleaning optics?

This statement under: WARNINGS – CAUTIONS:

Disposable natural cotton balls are a better choice than common lens cleaning tissue.

I have tried the distilled water/all natural cotton ball on reading glasses and a worthless scope and cleans all grease and fingerprints to a spotless shine?
